1 Claim. 1

This invention relates to cotton handling equipment and more particularly to new and useful improvements in suction telescopes for transferring seed cotton from conveyances into a gin.

The principal object of the invention is to improve upon the suspension means or mounting for suction telescopes, primarily by simplifying their installation on a gin house wall and through the provision of a mounting which permits of flexible connection between the horizontal transition tube supporting the suction telescope and the gin duct through which cotton is transported to the gin stands.

Another object of the invention is to provide an angle brace constituting the only needed support for the suction telescope and transition tube and which i capable of vertical adjustment from a conveniently accessible position on the ground to raise and lower the suction telescope while in no wise interfering with the ability of the latter to swing in a wide arc whose radius insures ample suction range under normal conditions.

Still another object of the invention is to provide means in the elbow junction between the suction telescope and transition tube to minimize frictional wear at this point caused by violent contact therewith of cotton and seeds under influence of suction, as Well as to reduce damage to the seed by such contact, which results in a lowering of the grade of the seed.

With the foregoing and other objects in view, the invention has reference to certain features of accomplishment to become manifest as the description proceeds, taken in connection with the accompanying drawings wherein:

Figure 1 is a perspective view of the invention shown installed on a gin house wall, the latter being broken away.

Figure 2 is a top plan view.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Figure 4 is a transverse sectional view of the suction telescope taken on line 4-4 of Figure 1.

Figure 5 is a sectional view of the elbow joining the suction telescope and transition tube, and

Figure 6 is a side elevational view of a modified form of supporting means on a reduced scale.

Continuing with a more detailed description of the drawing, reference numeral Ill denotes a wall,

usually that of a gin house in which the cotton cleaning and ginning equipment is installed. In this wall an opening is made to accommodate the flanged coniform section of a diaphragm housing, the said section being stationary in the wall l0 and in communication with a duct l2, leading to the gin stands, cleaners or storage, not shown, within the gin house.

Surrounding the flange of the housing section H is a ring I3. This ring is attached to the flange by means of diametrically opposed pivot pins l4 so disposed that the ring will oscillate on a horizontal axis defined by the pins.

A substantially funnel shaped, rubber diaphragm I5 is secured about its perimeter to the housing flange by a retaining ring |6 having annularly spaced bolt holes in register with like holes in the diaphragm and flange to receive bolts IT. The neck portion I8 of the diaphragm is formed with an annular bead I9 and a collar 29 surrounds the neck to constrict the same onto the end of a transition tube 2 The bead I9 not only serves to reinforce the neck portion of the diaphragm but also prevents the rubber from being displaced from under the retaining collar 2|] as the tube 2| is manipulated, as permitted by the high flexibility of the diaphragm |5.

Afiixed to the transition tube at one end is an angular brace 22 (Fig. 1), the opposite end of the brace being secured to the ring l3 at a point spaced from either of the pivotal pins l4. Thus, a form of gimbal mounting is efiected to attach the transition tube 2| to the diaphragm housing To support the transition tube 2| for swinging displacement on a horizontal plane as well as for vertical adjustment, a pair of downwardly convergent members 23 constitute an angular supporting arm. The upper ends of the members 23 lie one on each side of the tube 2| and each is connected to the tube through the medium of a pivotal pin 24. The pivot pins are in the form of bolts threaded into bosses 25, welded or otherwise alflxed to a collar or yoke 26 secured to the tube 2|. The convergent lower ends of the arm members 23 are pivotally retained by a bolt 21, extending through a sleeve or bushing 28 (Fig. 3), the latter being a part of or welded to a collar 29.

The collar 29 is interiorly threaded so as to be controlled in its longitudinal movement on a threaded rod 30, the latter being journaled at its upper and lower ends in vertically spaced brackets 3|. The lower end of the screw rod 30 carries a universal joint 32 (Fig. 1) and to the lower section of the universal joint is pivoted the upper end of a crank 33. The arm of the crank is held against other than rotative movement by a bracket 34, affixed to the wall ID, as are the mounting members 3| of the screw rod 30.

It is clearly apparent from the foregoing that by rotating the crank 33, the screw rod 39 will be rotated to cause the collar 29 to travel up and down thereon, thereby raising and lowering the transition tube 2| through the medium of the supporting arm 23. The weight of the tube 2| and its dependent elements to b presently described, which ordinarily would be borne by the screw rod 30 is actually assumed by a guide rail whose ends are welded to the mounting brackets 3| of the screw rod. By virtue of the V-shape of the guide rail 35 in which the collar 29 operates, frictional resistance between these elements is materially reduced.

The outer end of the transition tube 2| carrles an elbow 36 on which is formed an annular flange 31. A rubber diaphragm 38, which may be identical to and interchangeable with the diaphragm I5, is secured at its perimeter to. the flange 31 of the elbow by means of bolts 39 passing through a retaining ring 40. of the diaphragm is slipped over the upper end of the. upper section at of the suction telescop A ring clamp 42 embraces the neck of. the diaphragm. above the. bead 43 thereof and secures the diaphragm. onto. the suction telescop The bead 43: serves in the. capacity of a. shock absorber or bumper for the upper end of; the lower. e escope section 44: when the, latter is moved. upwardly.

The lower section 4A; of the suction telescope is slidable longitudinally on the exterior of the upper section, in a conventional manner and carries on its lower end a collar 65., to which is welded, in circumferentially spaced. relationship, a. series: of agitating fingers 45, certain of which are parallel with the longitudinal. axis of: the telescope. throughout their lengths. while the remainder are curved outwardly. These fin ers are effective to dislodge packed. cotton so that it may be readily caught up in the suction. and drawn upwardly through. the. telescope. Suitable manipulating handles 41: are provided on the. lower telescope section. at a point. spaced upwardly from its. lower end.

The velocity in the upward passage of material through the telescope causes the. same to strike curve of: the elbow 36. with considerable violence. This results in some damage, especially to seed, cracking them and reducing th ir grade. To minimize such damage. a. coverin 4:. of rubber is. placed on the underside: of the curve in the lbow and: is held place: by a rectangular, curved-frame 49 and screws 50. The material in passing through the. elbow will. strike the rubber covering andthus the shock of; con,- tact will. be cushioned, resulting in a protection not only for the commodity but also. obviates requirement. for replacement; of frictionally worn elbows.

The suction telescope is provided; with .a. counterbalance consisting of; a. pair of: cables; 5 I, their upper endsv being securedv to diametrically opiposed eyes 52-, on the upper end; of the lower telescope section 4'4; The. cables. then pass; over pulleys 53, mounted on the flange of the elbow 36, thence across to the wall It and; over pulleys. 54 thereon. The cables extend downwardly along the wall In. and. on each side of the mounting for the adjusting screw 30 andon'ea-ch cable is suspended a weight 55,.

In Figure 615 shown on reduced scale a modified form of means for suspending the suction telescope. The same reference numerals are em- The neck 4 ployed to designate like parts in th preceding views but the supporting arms 23 for the transsition tube 2| are substituted by a cable 58, one end of which is aifixed at 51 and extends over a pulley 58 attached to a yoke 59 on the transition tube 2|. The cable then extends rearwardly and over pulleys 60 and 60a, aifixed to the inside and outside surfaces respectively of the gin house wall 10, thence downwardly at an angle to escape the transporting; duct;- I2 and is wound on a Windlass 6 I. By operating the windlass, the outer end of the transition tube and consequently the suction telescope, is raised and lowered.

The described arrangement obviates the n cessity for an elaborate and costly mounting for -a suction telescope yet provides a highly flexible system for transferring cotton and other commodities from one point to another, allowing for maximum range of the suction end of the telescope. and operable with minimum e1- ort.

Manifestly; the construction as. shown and described; is capableof some modification and such modification. as. may be construed to fall within. the scope and meaning of the appended claim is also considered to be within the. spirit and intent of. the invention.

What is claimed is In an adjusting. support for; a pneumatic. material handling pipe the combination comprising a vertical: support for said pipe, a yoke embracing said pipe having oppositely directed. pivotal pins, a pair of upwardly divergent angular arms pivoted at their upper ends. to the pivoted pins of. said yoke, an interiorly threaded. collar carried by the lower ends of said arms, a. pair of vertically spaced brackets aflixed to saidv vertical support below said. pipe, a. screw rod having its ends. rotatably journaled in said brackets and on which said collar is: adapted. tomove longitudinally, a. substantially v-shaped. guide. rail welded at its ends. to said brackets and: adapted to. be. engagedby said collar toassume. the. weight of said pipe imposed on said: screw rod through said: arms, a universal jointv carried by the lower endof said screw. rod, a crank connected to said; universal joint for rotating said screw rod and means. embracing the. shank or said crank to hold the same against other than rotative movement to raise and lower said pipe.
